To all whom it. may-concern I Be a known that 1, my ri Ghovus,"a

. citizen of the Unit'ed States, residing. at Portland, in the county of Multnomah and 1 interlockin tures, and t e objects 'of'm1y Wil dli

State ofOregon, have invented a new and useful Interlocking Building-Block, of

which the following'is a specification...

My invention relates to improvements 1n building blocks for toy strucinvention .are to provide blocks which permit the construction of a large variety of structures of pleasing appearance and of suficient rigidity to allow handling without danger of collapse.

' ll attain these objects by the means illus trated in the accompanying drawing in which-.

Figure I shows my blocks assembled into a structure, in this case a house, Figs. H to XIV represent .a limited variety of individual pieces to illustrate the principle on which my invention is'based.

Similar numerals refer to similar parts throughout the several views.

The material employed 1n the manufacture of my blocks. is, referably, wood althoggh any other suitable substance may be use Tn thickness all the members are equal but in width, they conform to a certain system, while the length varies according to requirements, asdo also the number and disposition of notches in the individual mem-.

ers. a

According to aforementioned system my blocks are divided into three groups.

The first group comprises members of sin gle width having one or more square notches on one longitudinal edge only. Figs. ill, TH and TV represent samples of this grou 1 They are chiefly used as starting and finis in members for vertical was, columns, chimneys, etc.

' The second group com rises members of double width; their lengt and the number and location of notches vary according to requirements, specimen being shown in the drawing under Figs. V, VT and Vllll. ll/llem-* bers of this group form the major portion of vertical walls, built-up columns, china-- neys, etc. The pieces designated as Figs.

' lflllll, l and. K also belong to this group though being used in the eonstructlon of gables, one or both of their ends are cut resenting the suppor'tin structure.

rnrnnnoonrne nurnnrne-nrocn notches according to requirements.

Fig. Xlllll requires special notice. It is a short member of the second group but the twonotches, located opposite each other, are of double width to receive two members side I Patented July 2, ram.- Application fi1ed November 5,1917. Serial No. $00,382.

by side; as for instance in connecting pieces glike. Fig. TV into a continuous fence, bar

rier or similar structure with Fig. lllll reppost.

The p1ece in Fig. X also has a special function, and that is, to interlock two members, one above the other, only one of which is provided with a notch. Fig. TV bein in width midway between group one an two, its center portion 1, when dropped into notch 2.-of Fig. Vllll for example, will not project above edge 3, so that a piece like Fig. TV with its edge% can join closely to edge 3, yet will be prevented from lateral motion, at least, by projections 5 and 6 of Fig. XIV.

Referrin now to 'Fig. .l[, the use of my building b ocks will be clearly understood. At point '2 a suitable member of the first group is laid on the floor; at 8, with end notches interlocking a suitable member of the second group is laid across the former; across the latter again amember of the second'grou is laid, and so on until the desired heig t is obtained, when a member of the first group may be used to level ed the ere doors 9 or windows 10, 11 or 12 are desired, pieces Fig. V may be employed to interlock the ends abuttin the openings. At the point 13 use is ma e of Fig. Vllllll. Point it shows the application of Fig. Numerals l5 and lfi'indicate where members of the third group are used as roofs. It will be noted that the notches in members of the third group are set back I and Structures,

terlocked at the top make very suitable porch columns and roof supports.

Having thus described my invention .it

will be seen that my objects have been accomplished; and, though it is not practicable to show all the possible variations in blocks I reserve to myself the right to change minor details without violating the spirit of my invention.-

I claim 1. In interlocking buildin blocks of the character described, the com 'gle, double and triple width elements into a toy structure designated -as- Fig. I, the w single and double width elements forming columns and chimneys, the triple width elements forming slopin roofs,

the walls, gables,

said'roofs having a pronouncedover an at their gable ends, substantially as'descri ed.

2. As an article of manufacture, -interlocking building blocks slantingly,

ination of sir'iof equal thickness but various lengths, having a width approximately four times their thickness, having one or more square notches either en'one or both of their longitudinal edges, and having either one or both of their ends cut with the direction of the notches adjacent to the slant being parallel to said slant.

3. As an article of manufacture, an interlocking building block, having two square notches opposite each other and vthe width of each notch equaling twice the thickness of the block; said block being designated as Fig. XIII. 4. As an article of manufacture, an interlocking building block, having a width approximately three times, and a length approximately four times its thickness, havin i two square notches opposite each other, an

designated as Fig. XIV.
